Download the elevation data from the following website:
The area around Mt. Everest is found in the datafiles:
N27E086.hgt N27E087.hgt N28E086.hgt N28E087.hgt
which can be found in rows 26 and 27 and columns 86 and 87 in the big table on that website.
Now write a function that can read these data into a numpy array. Then write a function that can make a "heatmap" (image, where color = height) of this area. Plot this.
Next make a 3-D plot using the plot_surface() function of pyplot (or any other method of your choice), that you can rotate with the mouse.
